Hey ! Thanks a lot to both of you for sharing !
I did build on both your codes, and added the possibility to add a rating to a reading, which I use through a folder of bookmarklets

Code is here for those interested : https://github.com/ycouble/readingList

That's a super cool extension to it, thanks for sharing!

the power of open source! 💪
